Two pipes, equal in length, are each open at one end. Each has a fundamental frequency of 479 Hz at 18 C. In one pipe the air temperature is increased to 21 C. If the two pipes are sounded together, what beat frequency results?
Frequency is given by
<br>f = velocity / wavelength
<br>velocity of sound is dependent on temperature. It is given by
<br>v = 331+0.6T .
<br>Let V1 = 331 ...
